Clustered Naive Bayes
… possible? In this thesis, I present the Clustered Naive Bayes classifier, a hierarchical extension of the classic Naive Bayes classifier that ties several distinct Naive Bayes classifiers by placing a Dirichlet Process prior over their parameters. A priori, the model assumes that there …

Clustered wireless sensor networks
… This dissertation defines and studies clustered WSNs, WSNs whose topology due to the deployment procedure and the application requirements results in the phenomenon of clustering or clumping of nodes. The first part of this dissertation analyzes a range of topologies of clustered WSNs …

Latent Clustered Causal Models
… presence of latent variables. We define latent clustered causal models as a particular restriction on directed graphical models with latent variables and corresponding clusters of observed nodes, characterized by edges between only observed and latent variables. We discuss this model’s …

Crossings in Clustered Level Graphs
Clustered graphs are an enhanced graph model with a recursive clustering of the vertices according to a given nesting relation. This prime technique for expressing coherence of certain parts of the graph is used in many applications, such as biochemical pathways and UML class diagrams. For directed …

Techniques for handling clustered binary data
… decades there has been increasing interest in clustered studies and hence much research has gone into the analysis of data arising from these studies. It is erroneous to treat clustered data, where observations within a cluster are correlated with each other, as one would treat independent …

Reducing pause times with clustered collection
Clustered Collection reduces garbage collection pauses in programs with large amounts of live data. A full collection of millions of live objects can pause the program for multiple seconds. Much of this work, however, is repeated from one collection to the next, particularly for programs that …

Load Balancing in NetApp’s Clustered Storage Systems
To address the problem of load balancing in NetApp’s storage system, this thesis aims to design and implement an algorithm that results in more evenly distributed cluster reconfigurations with minimal disturbance to clients’ workloads. I implement three different greedy algorithms to find a more …

Optimized multi-superframe scheduling for clustered wireless sensor networks
Since the power source for wireless sensor networks (WSN) is mainly from batteries, prolonging network life is an important requirement of the network. Hence, clustering algorithms are employed to decrease the number of packets in the network via data aggregation as well to reduce packet network …

Analysis of Models for Longitudinal and Clustered Binary Data
… and statistical analysis of longitudinal and clustered binary data. Such data consists of observations on a dichotomous response variable generated from multiple time or cluster points, that exhibit either decaying correlation or equi-correlated dependence. The current literature addresses …

Clustered Layout Word Cloud for User Generated Online Reviews
… reading process. In this thesis, we present the clustered layout word cloud -- a text visualization that quickens decision making based on user generated reviews. We used a natural language processing approach, called grammatical dependency parsing, to analyze user generated review content and …

Confidence Interval Estimation of Cumulative Incidence for Clustered Competing Risks
In a cluster randomized trial studying a primary outcome patients are sometimes exposed to competing events. These are risks that alter the probability of the primary outcome occurring. Traditional methods of estimating the cumulative incidence for an outcome and its associated confidence interval …

A clustered back-bone for routing in ad-hoc networks
In the recent years, a lot of research work has been undertaken in the area of ad-hoc networks due to the increasing potential of putting them to commercial use in various types of mobile computing devices. Topology control in ad-hoc networks is a widely researched topic; with a number of …

The roles of clustered membrane proteins in T-cell signaling
… islands or protein clusters. The roles of these clustered proteins remain to be established. For my thesis, to gain insights into the roles of protein islands in early T cell signaling, I have focused on important clustered proteins such as the T-cell receptor (TCR) and Linker of activated T …

The Clustered Insulated Gate Bipolar Transistor (CIGBT) — from concept to manufacturing
In this thesis the novel power device called Clustered Insulated Gate Bipolar Transistor (CIGBT) is developed from concept to a pre-manufacturing product. The CIGBT uses MOS gate control over a thyristor action to achieve low conduction losses. A “Capacitive” turn-on mechanism ensures a smooth turn …
